TF-IDF and k-Means Clustering in Amazon Reviews¶

#Importing thelibraries

import numpy as np
import pandas as pd

import matplotlib.pyplot as plt
import seaborn as sns
sns.set()

from sklearn.metrics import pairwise_distances

import re
from nltk.corpus import stopwords

import warnings
warnings.filterwarnings("ignore")

pd.set_option('display.max_columns', None)

Explore and clean the data¶

#Loading the data and checking the shape
data = pd.read_csv("amazon-reviews.csv.bz2", sep = '\t')
data.shape

(205331, 4)

#Checking for NA values
data.dropna(inplace = True) # dropping the NA values
data.head()

Looking for duplicates¶

mult_reviews = (data.groupby('review', as_index = False).size().
                sort_values(ascending = False).reset_index(name = 'no_of_reviews'))

plt.figure(figsize = (10, 6))
sns.countplot(x = mult_reviews['no_of_reviews'] > 1)

<matplotlib.axes._subplots.AxesSubplot at 0x29454c94a58>

From the above graph we could see that there are some reviews repeated more than once. We will drop the duplicates to analyze the data better and avoid reptitions.

data.drop_duplicates(inplace = True)
data.shape

(195752, 4)

#Checking for sample 1000 reviews
np.random.seed(42)
review = pd.DataFrame(data['review'].sample(1000)).reset_index() # sampling 1000 reviews for the initial analysis
review.drop("index", axis = 1, inplace = True) # dropping the index column
review.head(10)

Let us perform TF-IDF on the reviews and we will have some better idea on how many clusters we would like to have.¶

Implement TF-IDF Transform¶

def quote_to_words(raw_quote):
    #removing raw letters,numbers,punctuations
    letters = re.sub("[^a-zA-Z]"," ",raw_quote)
    #creating an array , resolving whitespaces
    words = letters.lower().split()
    #create an array of stopwords so that we don't have to access corpus to search for a stopword
    stop = set(stopwords.words("english"))
    #removing stopwords from the raw_review
    meaningful_words = [w for w in words if w not in stop]
    #return a string with only the words that are important
    return(" ".join(meaningful_words))

clean_reviews = []

for i in range(review.review.size):
    clean_reviews.append(quote_to_words(review.review[i]))

review_series = pd.Series(clean_reviews)

#Creating work data
work_data = pd.DataFrame(review_series)

#Combining the fresh and quotes columns
work_data.rename(columns = {0 : 'review'}, inplace = True)

work_data.head()

from sklearn.feature_extraction.text import CountVectorizer

vectorizer = CountVectorizer()
X = vectorizer.fit_transform(work_data['review']).toarray()
X.shape

(1000, 6598)

BOW = pd.DataFrame(X, columns = vectorizer.get_feature_names())
BOW.head()

print("Counting the actual number of words :")
print(len(BOW.columns))

Counting the actual number of words :
6598

Most commonly occurring words in the reviews¶

BOW.apply(np.sum, axis = 0).sort_values(ascending = False).head(10)

Calculating tf-idf for every word in the reviews to find the important words¶

BOW['total_words'] = BOW.sum(axis = 1)
BOW_tf_idf = BOW.apply(lambda x: ((x/BOW['total_words']) * np.log((1+len(BOW))/(x+1))))
BOW_tf_idf.drop('total_words', axis = 1, inplace = True)
BOW_tf_idf.head()

Using sklearn tfidf vectorizer¶

from sklearn.feature_extraction.text import TfidfVectorizer
vec = TfidfVectorizer(stop_words='english')
XX = vec.fit_transform(work_data.review).toarray()
bow_vec = pd.DataFrame(XX, columns = vec.get_feature_names())
bow_vec.head()

Implement k-Means clustering¶

print("The norm of the tfidf matrix is:", round(np.linalg.norm(X), 2))

The norm of the tfidf matrix is: 272.22

The algorithm here is considering the TF-IDF property of the words to group the words into clusters.In TF-IDF, we calculate the frequency of a word occuring in the document and we multiply this with the IDF of the word across all the reviews in the document.¶

Firstly we randomly assign centroids in initialise_centroids function and we try to find the proximity of the words by means of cosine distances in order to find which words fall in which cluster using assign_clusters function. Then we assign the words to those clusters in order to minimize the within cluster sum of squared distances. This is done using update_centroid function and assign_cluster function again. This process keeps on repeating and in every iteration, the clusters are re calculated.So with every iteration, the centroids get optimized such that the distance within the clusters is minimum and teh distance within different clusters is maximized.¶

We have also calculated the norm of the reviews and cluster centers(centroids)¶

kmeans_model = Kmeans(3, seed = 42, max_iter = 200)

fitted = kmeans_model.fit_kmeans(X)

The norm of the centroids is: 22.91
Running Model Iteration 0 
Running Model Iteration 100 
Model finished running

#Th predicted function returns the cluster labels

predicted = kmeans_model.predict(X)

pred_df = pd.DataFrame(predicted, columns = ['cluster'])

print("The condition number cluster zero:", round(np.linalg.cond(X[pred_df[pred_df.cluster == 0].index]),2))
print("The condition number cluster one:", round(np.linalg.cond(X[pred_df[pred_df.cluster == 1].index]),2))
print("The condition number cluster two:", round(np.linalg.cond(X[pred_df[pred_df.cluster == 2].index]),2))

The condition number cluster zero: 310.21
The condition number cluster one: 31.9
The condition number cluster two: 22.81

Analyzing the clusters¶

#Appending the cluster reviews to the original dataset
review['cluster_labels'] = predicted

review[review['cluster_labels'] == 0]

g = review.groupby('cluster_labels')

pd.set_option('display.max_colwidth', -1)
g.get_group(0).head(10)

From looking at the samples of the first cluster, we could see that it contains baby and beauty products with an inclination towards baby products. This cluster has the maximum number of samples.

g.get_group(1).head(10)

From the above cluster we could see that this cluster also has both baby and beauty products but here with inclination towards beauty products.

g.get_group(2).head(10)

This cluster has the least number of samples and contains baby and beauty product reviews. With more number of samples, probably the algorithm would be able to cluster better.

r=review.review.to_frame()
for i in range(3,10):
    #def clusters(k_value):
        print("K value :",i)
        
        kmeans_model = Kmeans(i, seed = 42, max_iter = 200)
        fitted = kmeans_model.fit_kmeans(X)
        #Th predicted function returns the cluster labels

        predicted = kmeans_model.predict(X)

1  I love this mascara.\n\nIt's super easy to apply and doesn't clump.  My lashes look both thicker and darker.  I've also had no eye irritation.\n\nThe want is comfortable as well.\n\nNo smudging, no raccoon eyes, and I find that I don't need to reapply it during the day.  Once in the morning and that's it.\n\nVery pleased with this!

5  This monitor is fantastic. The picture is very clear, even in the dark, and the sound is super sensitive. The battery lasts a long time, and after almost 2 years of daily use it is still working perfect and we have had zero problems with it. Every once in a while we'll get a tad bit of static, but the house is pretty big, so it's expected. This was definitely worth the money.   
6  So pleased with this.  My mother purchased a different kind for her house, and the quality just didn't compare.1  The single piece of molded foam makes for super easy cleaning.2  The pee guard is great to keep messes from happening.3  The design is genius.  My son clearly feels more supported and comfortable on this than other types.

2   I have tried too many different diapers/ brands/ systems to list and these are one of my favorites! I bought one originally just to try it and I've bought 4 more since. They also make wonderful newborn diapers call Tini Fit Tots Bots.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                  
15  I have owned this toy twice so far. I bought one when my daughter was 6 months old and thought she would love it. She ended up not liking it at all. She was not a "bouncy" baby. We ended up taking it back for an exersaucer instead. Fast forward 2 years later I had my son, he just turned 6 months and he's a bouncer. The exersaucer is not his thing, I ended up buying this again. He LOVES this so much. Onto the review of the jumperoo nowLike every other baby toy it takes up room, I do like that it folds down a bit but still bulky so be prepared if you have a small apartment. It has adjustable straps to grow with baby. My son is on the number 2 setting at 6 months. 27 1/2 inches. The seat cover is easy to get off and wash which is great. Very easy to clean most parts. The toys on the jumperoo are four different spinners...lizard, sun, rainbow disk and a small one with an animal sticker. I think they could have come up with some else, four is over kill. There is a peekaboo tiger which is hard for the baby to press and it doesn't come up far enough. My son doesn't even bother with that. A musical trio which is ok the animals dont do anything except the elelphant which the baby has to turn to see its face. The lights gets the babys attention. The other toy Is a bug on a long stick...in the picture it shows standing up..our flops over so half the time it hangs off the side. I think some of the toys could be better, it would be awesome if they made a jumperoo with interchangeable toys. Especially some bigger crinkle ones..I have yet to meet a baby who doesn't like crinkles lol What I liked most and it's something that bugs me on a lot of other toys but this one doesn't have this problem is volume control. I love that it is not loud! Finally they figured out babies are not deaf.  Overall  it's a cute toy and will def give mom a break to do some dishes. I would also recommend waiting until 6 months to buy the toy it's not for all babies. If you baby is a jumper I would recommend it if not an exersaucer would do fine.

8   I bought this for my little girl when she was 12 months old.  I never used exersausers much with my three older children because they were very mobile very young and crawled/walked around to different pile of toys I had laying around for them.  However, Anna wasn't so mobile, so I got this for her.SHE LOVED IT!  I didn't even ever put any batteries in it.  She would play with it for hours and loved all the toys.  It really does grow with the child.One bad thing I noticed was that ours came with a food tray that never stayed on right.  Plus, who wants food near the exersaucer?  Soft food (baby food, etc.) would get smeared all over it; hard food (cheerios, etc.) would get crushed into it and shoved into little crevasses...never did understand the food tray coming with a toy??  I don't think it was any reason to dock it a star, though.This is a great toy!   
10  Bought this and wish I had not. Have had it for three months, and my husband uses it a few times a week and when he does it easily shows any sweat once it dries. The quality is poor and the stitching is fraying / coming apart. Not impressed.

4  Cute blanket, great materials. The green center is a terry cloth material which is great for soaking up the drool that goes with teething. Not shown in the picture is a green ring attachment that goes through the purple corner. The ring itself isn't great, the opening is too large to keep it attatched, but it was easily swapped out with another ring link. I liked having the option to attach it to the carseat or stroller so it wasn't dropped though.   
6  So pleased with this.  My mother purchased a different kind for her house, and the quality just didn't compare.1  The single piece of molded foam makes for super easy cleaning.2  The pee guard is great to keep messes from happening.3  The design is genius.  My son clearly feels more supported and comfortable on this than other types.

0  I love this seat, it's so easy to use and most importantly clean.  You can also remove the tray,and keep the baby buckled in while you tidy up.  Fabulous                                                                                                                                                                                       
1  I love this mascara.\n\nIt's super easy to apply and doesn't clump.  My lashes look both thicker and darker.  I've also had no eye irritation.\n\nThe want is comfortable as well.\n\nNo smudging, no raccoon eyes, and I find that I don't need to reapply it during the day.  Once in the morning and that's it.\n\nVery pleased with this!

2   I have tried too many different diapers/ brands/ systems to list and these are one of my favorites! I bought one originally just to try it and I've bought 4 more since. They also make wonderful newborn diapers call Tini Fit Tots Bots.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                  
15  I have owned this toy twice so far. I bought one when my daughter was 6 months old and thought she would love it. She ended up not liking it at all. She was not a "bouncy" baby. We ended up taking it back for an exersaucer instead. Fast forward 2 years later I had my son, he just turned 6 months and he's a bouncer. The exersaucer is not his thing, I ended up buying this again. He LOVES this so much. Onto the review of the jumperoo nowLike every other baby toy it takes up room, I do like that it folds down a bit but still bulky so be prepared if you have a small apartment. It has adjustable straps to grow with baby. My son is on the number 2 setting at 6 months. 27 1/2 inches. The seat cover is easy to get off and wash which is great. Very easy to clean most parts. The toys on the jumperoo are four different spinners...lizard, sun, rainbow disk and a small one with an animal sticker. I think they could have come up with some else, four is over kill. There is a peekaboo tiger which is hard for the baby to press and it doesn't come up far enough. My son doesn't even bother with that. A musical trio which is ok the animals dont do anything except the elelphant which the baby has to turn to see its face. The lights gets the babys attention. The other toy Is a bug on a long stick...in the picture it shows standing up..our flops over so half the time it hangs off the side. I think some of the toys could be better, it would be awesome if they made a jumperoo with interchangeable toys. Especially some bigger crinkle ones..I have yet to meet a baby who doesn't like crinkles lol What I liked most and it's something that bugs me on a lot of other toys but this one doesn't have this problem is volume control. I love that it is not loud! Finally they figured out babies are not deaf.  Overall  it's a cute toy and will def give mom a break to do some dishes. I would also recommend waiting until 6 months to buy the toy it's not for all babies. If you baby is a jumper I would recommend it if not an exersaucer would do fine.

8   I bought this for my little girl when she was 12 months old.  I never used exersausers much with my three older children because they were very mobile very young and crawled/walked around to different pile of toys I had laying around for them.  However, Anna wasn't so mobile, so I got this for her.SHE LOVED IT!  I didn't even ever put any batteries in it.  She would play with it for hours and loved all the toys.  It really does grow with the child.One bad thing I noticed was that ours came with a food tray that never stayed on right.  Plus, who wants food near the exersaucer?  Soft food (baby food, etc.) would get smeared all over it; hard food (cheerios, etc.) would get crushed into it and shoved into little crevasses...never did understand the food tray coming with a toy??  I don't think it was any reason to dock it a star, though.This is a great toy!   
10  Bought this and wish I had not. Have had it for three months, and my husband uses it a few times a week and when he does it easily shows any sweat once it dries. The quality is poor and the stitching is fraying / coming apart. Not impressed.

4  Cute blanket, great materials. The green center is a terry cloth material which is great for soaking up the drool that goes with teething. Not shown in the picture is a green ring attachment that goes through the purple corner. The ring itself isn't great, the opening is too large to keep it attatched, but it was easily swapped out with another ring link. I liked having the option to attach it to the carseat or stroller so it wasn't dropped though.   
6  So pleased with this.  My mother purchased a different kind for her house, and the quality just didn't compare.1  The single piece of molded foam makes for super easy cleaning.2  The pee guard is great to keep messes from happening.3  The design is genius.  My son clearly feels more supported and comfortable on this than other types.

0  I love this seat, it's so easy to use and most importantly clean.  You can also remove the tray,and keep the baby buckled in while you tidy up.  Fabulous                                                                                                                                                                                                                                       
3  I love a good lip gloss and this is absolutely perfect.  The applicator has a small indentation which makes application easy.  This has a very light fruity scent.  This gloss glides on blissfully it is not sticky or too shiny.  I have medium skin tone and this color is perfect and I personally think will compliment any skin tone.  This is one of the best lip glosses I have used.

1   I love this mascara.\n\nIt's super easy to apply and doesn't clump.  My lashes look both thicker and darker.  I've also had no eye irritation.\n\nThe want is comfortable as well.\n\nNo smudging, no raccoon eyes, and I find that I don't need to reapply it during the day.  Once in the morning and that's it.\n\nVery pleased with this!   
16  WE LOVE THE PRINT.  THE BLANKET IS SUPER SOFT AND SUPER CUTE. WOULD RECOMMEND THIS BLANKET TO ANYONE FOR A LITTLE GIRL.

2   I have tried too many different diapers/ brands/ systems to list and these are one of my favorites! I bought one originally just to try it and I've bought 4 more since. They also make wonderful newborn diapers call Tini Fit Tots Bots.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                  
15  I have owned this toy twice so far. I bought one when my daughter was 6 months old and thought she would love it. She ended up not liking it at all. She was not a "bouncy" baby. We ended up taking it back for an exersaucer instead. Fast forward 2 years later I had my son, he just turned 6 months and he's a bouncer. The exersaucer is not his thing, I ended up buying this again. He LOVES this so much. Onto the review of the jumperoo nowLike every other baby toy it takes up room, I do like that it folds down a bit but still bulky so be prepared if you have a small apartment. It has adjustable straps to grow with baby. My son is on the number 2 setting at 6 months. 27 1/2 inches. The seat cover is easy to get off and wash which is great. Very easy to clean most parts. The toys on the jumperoo are four different spinners...lizard, sun, rainbow disk and a small one with an animal sticker. I think they could have come up with some else, four is over kill. There is a peekaboo tiger which is hard for the baby to press and it doesn't come up far enough. My son doesn't even bother with that. A musical trio which is ok the animals dont do anything except the elelphant which the baby has to turn to see its face. The lights gets the babys attention. The other toy Is a bug on a long stick...in the picture it shows standing up..our flops over so half the time it hangs off the side. I think some of the toys could be better, it would be awesome if they made a jumperoo with interchangeable toys. Especially some bigger crinkle ones..I have yet to meet a baby who doesn't like crinkles lol What I liked most and it's something that bugs me on a lot of other toys but this one doesn't have this problem is volume control. I love that it is not loud! Finally they figured out babies are not deaf.  Overall  it's a cute toy and will def give mom a break to do some dishes. I would also recommend waiting until 6 months to buy the toy it's not for all babies. If you baby is a jumper I would recommend it if not an exersaucer would do fine.

5  This monitor is fantastic. The picture is very clear, even in the dark, and the sound is super sensitive. The battery lasts a long time, and after almost 2 years of daily use it is still working perfect and we have had zero problems with it. Every once in a while we'll get a tad bit of static, but the house is pretty big, so it's expected. This was definitely worth the money.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                          
8  I bought this for my little girl when she was 12 months old.  I never used exersausers much with my three older children because they were very mobile very young and crawled/walked around to different pile of toys I had laying around for them.  However, Anna wasn't so mobile, so I got this for her.SHE LOVED IT!  I didn't even ever put any batteries in it.  She would play with it for hours and loved all the toys.  It really does grow with the child.One bad thing I noticed was that ours came with a food tray that never stayed on right.  Plus, who wants food near the exersaucer?  Soft food (baby food, etc.) would get smeared all over it; hard food (cheerios, etc.) would get crushed into it and shoved into little crevasses...never did understand the food tray coming with a toy??  I don't think it was any reason to dock it a star, though.This is a great toy!

4  Cute blanket, great materials. The green center is a terry cloth material which is great for soaking up the drool that goes with teething. Not shown in the picture is a green ring attachment that goes through the purple corner. The ring itself isn't great, the opening is too large to keep it attatched, but it was easily swapped out with another ring link. I liked having the option to attach it to the carseat or stroller so it wasn't dropped though.   
6  So pleased with this.  My mother purchased a different kind for her house, and the quality just didn't compare.1  The single piece of molded foam makes for super easy cleaning.2  The pee guard is great to keep messes from happening.3  The design is genius.  My son clearly feels more supported and comfortable on this than other types.

0   I love this seat, it's so easy to use and most importantly clean.  You can also remove the tray,and keep the baby buckled in while you tidy up.  Fabulous                            
18  It does the job, but in one travel, it had 2 holes probably from the way the airlines handle the things. But it does keep the car seat safe and clean. The quality is pretty good.

3  I love a good lip gloss and this is absolutely perfect.  The applicator has a small indentation which makes application easy.  This has a very light fruity scent.  This gloss glides on blissfully it is not sticky or too shiny.  I have medium skin tone and this color is perfect and I personally think will compliment any skin tone.  This is one of the best lip glosses I have used.   
7  These are so soft and cute. They are very gentle on babies skin. It's not scratchy or course like some of the other products out there. Highly recommended. Get's softer with each washing.

2  I have tried too many different diapers/ brands/ systems to list and these are one of my favorites! I bought one originally just to try it and I've bought 4 more since. They also make wonderful newborn diapers call Tini Fit Tots Bots.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                          
8  I bought this for my little girl when she was 12 months old.  I never used exersausers much with my three older children because they were very mobile very young and crawled/walked around to different pile of toys I had laying around for them.  However, Anna wasn't so mobile, so I got this for her.SHE LOVED IT!  I didn't even ever put any batteries in it.  She would play with it for hours and loved all the toys.  It really does grow with the child.One bad thing I noticed was that ours came with a food tray that never stayed on right.  Plus, who wants food near the exersaucer?  Soft food (baby food, etc.) would get smeared all over it; hard food (cheerios, etc.) would get crushed into it and shoved into little crevasses...never did understand the food tray coming with a toy??  I don't think it was any reason to dock it a star, though.This is a great toy!

5  This monitor is fantastic. The picture is very clear, even in the dark, and the sound is super sensitive. The battery lasts a long time, and after almost 2 years of daily use it is still working perfect and we have had zero problems with it. Every once in a while we'll get a tad bit of static, but the house is pretty big, so it's expected. This was definitely worth the money.

4  Cute blanket, great materials. The green center is a terry cloth material which is great for soaking up the drool that goes with teething. Not shown in the picture is a green ring attachment that goes through the purple corner. The ring itself isn't great, the opening is too large to keep it attatched, but it was easily swapped out with another ring link. I liked having the option to attach it to the carseat or stroller so it wasn't dropped though.   
6  So pleased with this.  My mother purchased a different kind for her house, and the quality just didn't compare.1  The single piece of molded foam makes for super easy cleaning.2  The pee guard is great to keep messes from happening.3  The design is genius.  My son clearly feels more supported and comfortable on this than other types.

This is one of the best lip glosses I have used.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                       
17  VERY happy with this spray with my hair.  The best test for me was HOW it held my hair-styling in place during an outdoor concert (breezy & warm) without being sticky and looking stiff or unnatural.  Wow!\n\nDue to aging and some thyroid issues, I've been losing quite a bit of hair.  What used to be full is currently thin in comparison.  Thankfully, I have some natural curl/wave.  Wanting my hair up (high pony tail) with softness around the bangs and face, I styled and sprayed.  Very natural (yay!) and soft looking.  I also spritzed the pony-tail curls.  After sleeping with it (in same style), I was even more impressed that the curl remaining in my pony tail the next morning.  When I took it down, my whole head of hair had more volume/hold and I could get away with no re-washing it (time crunch).\n\nI am "scent sensitive" and the Calista spray was not strong, allergy-inspiring, and any scent dissipated quickly.  My sensitive-nosed husband with whom I sat next to (in the car & the concert), never said, "what's that smell?"... which is the TRUE test!\n\nI am very happy with this spray and look forward to testing it with other styling.  A little goes a long way, so I'm encouraged the price will equal its value.  Fun!

10  Bought this and wish I had not. Have had it for three months, and my husband uses it a few times a week and when he does it easily shows any sweat once it dries. The quality is poor and the stitching is fraying / coming apart. Not impressed.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                       
12  - they are waaay too high to be useful as snack traps.- once they get gross with soggy goldfish there is no way to clean them because they stay permanently attached.  So unlike other strollers where you can easily pop out the snack tray and hose it off in the sink, this one stays gross & you have to do your best with wet wipes.- it makes the folded configuration a little thicker- if the kids are buckled, the tray is so high they can't reach it.  (this goes with my first point)- it is soooo difficult to install & one screw on mine constantly falls off so I finally just left it off.- too expensive- it's impossible for the kids to climb in.  a 2 year old & 4 year old both have the same problem.  they can't go under it because humans don't twist that way (even them who can climb on anything) so my 2 year old son tries to climb over it if I don't get to him quick enough & it gives me a heart attack each time I catch him trying that b/che'll fall & hit his head one of these days if I don't grab him quick enough.  So I have to lift my heavy 4 year old &  2 year old in EVERY TIME.  lift them in, lift them out, lift them in, lift them out.  and it's not just a short lift, you have to lift them high up and they have to contort themselves to fit under it.awful design.  Bob folks - you gotta fix this.  this design hasn't changed for years.  Change the seats so they sit straight upright and add a snack tray that will funcion as a snack tray.  I know you can do it :)

2   I have tried too many different diapers/ brands/ systems to list and these are one of my favorites! I bought one originally just to try it and I've bought 4 more since. They also make wonderful newborn diapers call Tini Fit Tots Bots.   
13  My child is scared of &#34;big potties&#34;. When we are on the road or out shopping, this is the lifesaver for &#34;I have to pee now daddy!&#34;. We love it.

5   This monitor is fantastic. The picture is very clear, even in the dark, and the sound is super sensitive. The battery lasts a long time, and after almost 2 years of daily use it is still working perfect and we have had zero problems with it. Every once in a while we'll get a tad bit of static, but the house is pretty big, so it's expected. This was definitely worth the money.   
25  This design is a big improvement over string swings' past designs head stock fits snugly in the well made cradle.  quality wood constructtion and the rubber material used feels nice to the touch.  I will buy more if I get another guitar.

4  Cute blanket, great materials. The green center is a terry cloth material which is great for soaking up the drool that goes with teething. Not shown in the picture is a green ring attachment that goes through the purple corner. The ring itself isn't great, the opening is too large to keep it attatched, but it was easily swapped out with another ring link. I liked having the option to attach it to the carseat or stroller so it wasn't dropped though.   
6  So pleased with this.  My mother purchased a different kind for her house, and the quality just didn't compare.1  The single piece of molded foam makes for super easy cleaning.2  The pee guard is great to keep messes from happening.3  The design is genius.  My son clearly feels more supported and comfortable on this than other types.

0   I love this seat, it's so easy to use and most importantly clean.  You can also remove the tray,and keep the baby buckled in while you tidy up.  Fabulous                            
18  It does the job, but in one travel, it had 2 holes probably from the way the airlines handle the things. But it does keep the car seat safe and clean. The quality is pretty good.

1   I love this mascara.\n\nIt's super easy to apply and doesn't clump.  My lashes look both thicker and darker.  I've also had no eye irritation.\n\nThe want is comfortable as well.\n\nNo smudging, no raccoon eyes, and I find that I don't need to reapply it during the day.  Once in the morning and that's it.\n\nVery pleased with this!   
11  I ordered this for my new grandsons room at my home. I put it together and was kind of dissapointed at how it tipped over easily. So I actually put a waste basket in it to help it stand up and will use it for waste. I mean it works great to cover the trash can so it worked out. Just not sure if I would recomend.

3  I love a good lip gloss and this is absolutely perfect.  The applicator has a small indentation which makes application easy.  This has a very light fruity scent.  This gloss glides on blissfully it is not sticky or too shiny.  I have medium skin tone and this color is perfect and I personally think will compliment any skin tone.  This is one of the best lip glosses I have used.   
7  These are so soft and cute. They are very gentle on babies skin. It's not scratchy or course like some of the other products out there. Highly recommended. Get's softer with each washing.

8   I bought this for my little girl when she was 12 months old.  I never used exersausers much with my three older children because they were very mobile very young and crawled/walked around to different pile of toys I had laying around for them.  However, Anna wasn't so mobile, so I got this for her.SHE LOVED IT!  I didn't even ever put any batteries in it.  She would play with it for hours and loved all the toys.  It really does grow with the child.One bad thing I noticed was that ours came with a food tray that never stayed on right.  Plus, who wants food near the exersaucer?  Soft food (baby food, etc.) would get smeared all over it; hard food (cheerios, etc.) would get crushed into it and shoved into little crevasses...never did understand the food tray coming with a toy??  I don't think it was any reason to dock it a star, though.This is a great toy!   
10  Bought this and wish I had not. Have had it for three months, and my husband uses it a few times a week and when he does it easily shows any sweat once it dries. The quality is poor and the stitching is fraying / coming apart. Not impressed.

14  Great bottle set, but my son is so rarely bottle fed that we actually ended up returning them. Think about how often you're going to be nursing, pumping, and bottle feeding before investing in lots of bottles and storage.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                   
21  i've had this bottle warmer for about 9 months now, and it hasn't broken down yet :)  initially i followed the instructions regarding how much water to put in to heat up certain amount of milk, and that worked fine when I was heating up 2 ounces earlier on.  As the volume increases, I find that I just had to add more water than usual to heat the milk up.  Nowadays i just use the entire water container to heat up 4 oz of milk.  my nanny uses it to heat up water too.  i haven't had any bottles that melt in it yet.  there was one time i forgot to put the basket back in and stuck a medela bottle in there by mistake and that caused some marring on the bottom of the bottle.  if you use the dr. brown bottles, just remember to take out the vent reservoir or the milk will travel up and leak out.the other thing is this thing collects hard water stains and calcium deposits on the bottle, so it kind of look dirty and brown.  i wipe it down from time to time, but i haven't had the time to completely get rid of it.  in all, for the price that i paid, i think it's worked pretty well.

They also make wonderful newborn diapers call Tini Fit Tots Bots.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                  
15  I have owned this toy twice so far. I bought one when my daughter was 6 months old and thought she would love it. She ended up not liking it at all. She was not a "bouncy" baby. We ended up taking it back for an exersaucer instead. Fast forward 2 years later I had my son, he just turned 6 months and he's a bouncer. The exersaucer is not his thing, I ended up buying this again. He LOVES this so much. Onto the review of the jumperoo nowLike every other baby toy it takes up room, I do like that it folds down a bit but still bulky so be prepared if you have a small apartment. It has adjustable straps to grow with baby. My son is on the number 2 setting at 6 months. 27 1/2 inches. The seat cover is easy to get off and wash which is great. Very easy to clean most parts. The toys on the jumperoo are four different spinners...lizard, sun, rainbow disk and a small one with an animal sticker. I think they could have come up with some else, four is over kill. There is a peekaboo tiger which is hard for the baby to press and it doesn't come up far enough. My son doesn't even bother with that. A musical trio which is ok the animals dont do anything except the elelphant which the baby has to turn to see its face. The lights gets the babys attention. The other toy Is a bug on a long stick...in the picture it shows standing up..our flops over so half the time it hangs off the side. I think some of the toys could be better, it would be awesome if they made a jumperoo with interchangeable toys. Especially some bigger crinkle ones..I have yet to meet a baby who doesn't like crinkles lol What I liked most and it's something that bugs me on a lot of other toys but this one doesn't have this problem is volume control. I love that it is not loud! Finally they figured out babies are not deaf.  Overall  it's a cute toy and will def give mom a break to do some dishes. I would also recommend waiting until 6 months to buy the toy it's not for all babies. If you baby is a jumper I would recommend it if not an exersaucer would do fine.

5   This monitor is fantastic. The picture is very clear, even in the dark, and the sound is super sensitive. The battery lasts a long time, and after almost 2 years of daily use it is still working perfect and we have had zero problems with it. Every once in a while we'll get a tad bit of static, but the house is pretty big, so it's expected. This was definitely worth the money.   
25  This design is a big improvement over string swings' past designs head stock fits snugly in the well made cradle.  quality wood constructtion and the rubber material used feels nice to the touch.  I will buy more if I get another guitar.

4  Cute blanket, great materials. The green center is a terry cloth material which is great for soaking up the drool that goes with teething. Not shown in the picture is a green ring attachment that goes through the purple corner. The ring itself isn't great, the opening is too large to keep it attatched, but it was easily swapped out with another ring link. I liked having the option to attach it to the carseat or stroller so it wasn't dropped though.   
6  So pleased with this.  My mother purchased a different kind for her house, and the quality just didn't compare.1  The single piece of molded foam makes for super easy cleaning.2  The pee guard is great to keep messes from happening.3  The design is genius.  My son clearly feels more supported and comfortable on this than other types.

0   I love this seat, it's so easy to use and most importantly clean.  You can also remove the tray,and keep the baby buckled in while you tidy up.  Fabulous                            
18  It does the job, but in one travel, it had 2 holes probably from the way the airlines handle the things. But it does keep the car seat safe and clean. The quality is pretty good.

1   I love this mascara.\n\nIt's super easy to apply and doesn't clump.  My lashes look both thicker and darker.  I've also had no eye irritation.\n\nThe want is comfortable as well.\n\nNo smudging, no raccoon eyes, and I find that I don't need to reapply it during the day.  Once in the morning and that's it.\n\nVery pleased with this!   
16  WE LOVE THE PRINT.  THE BLANKET IS SUPER SOFT AND SUPER CUTE.

3  I love a good lip gloss and this is absolutely perfect.  The applicator has a small indentation which makes application easy.  This has a very light fruity scent.  This gloss glides on blissfully it is not sticky or too shiny.  I have medium skin tone and this color is perfect and I personally think will compliment any skin tone.  This is one of the best lip glosses I have used.   
7  These are so soft and cute. They are very gentle on babies skin. It's not scratchy or course like some of the other products out there. Highly recommended. Get's softer with each washing.

8   I bought this for my little girl when she was 12 months old.  I never used exersausers much with my three older children because they were very mobile very young and crawled/walked around to different pile of toys I had laying around for them.  However, Anna wasn't so mobile, so I got this for her.SHE LOVED IT!  I didn't even ever put any batteries in it.  She would play with it for hours and loved all the toys.  It really does grow with the child.One bad thing I noticed was that ours came with a food tray that never stayed on right.  Plus, who wants food near the exersaucer?  Soft food (baby food, etc.) would get smeared all over it; hard food (cheerios, etc.) would get crushed into it and shoved into little crevasses...never did understand the food tray coming with a toy??  I don't think it was any reason to dock it a star, though.This is a great toy!   
10  Bought this and wish I had not. Have had it for three months, and my husband uses it a few times a week and when he does it easily shows any sweat once it dries. The quality is poor and the stitching is fraying / coming apart. Not impressed.

14  Great bottle set, but my son is so rarely bottle fed that we actually ended up returning them. Think about how often you're going to be nursing, pumping, and bottle feeding before investing in lots of bottles and storage.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                   
21  i've had this bottle warmer for about 9 months now, and it hasn't broken down yet :)  initially i followed the instructions regarding how much water to put in to heat up certain amount of milk, and that worked fine when I was heating up 2 ounces earlier on.  As the volume increases, I find that I just had to add more water than usual to heat the milk up.  Nowadays i just use the entire water container to heat up 4 oz of milk.  my nanny uses it to heat up water too.  i haven't had any bottles that melt in it yet.  there was one time i forgot to put the basket back in and stuck a medela bottle in there by mistake and that caused some marring on the bottom of the bottle.  if you use the dr. brown bottles, just remember to take out the vent reservoir or the milk will travel up and leak out.the other thing is this thing collects hard water stains and calcium deposits on the bottle, so it kind of look dirty and brown.  i wipe it down from time to time, but i haven't had the time to completely get rid of it.  in all, for the price that i paid, i think it's worked pretty well.

32  Every time I ordered one of these Babyletto items, (we bought a set) they arrived damaged. The company would not take it back and send me a new one, instead, they offered to send me all the damged parts for both the crib and changing station. The company had me send pictures to send me replacement parts, I feel that it was a waste of precious time to deal with it. We assembeled and disassembeled a couple of times and then we just gave up and stored the parts in storage.  The quality is so that you cannot mess with it too much.I like the Design, but it's hard to find bumpers that fit this crib properly. The drawer on the bottom is great and this crib is perfect for small spaces. I wish it was made with a bit of a better quality.

0	I love this seat, it's so easy to use and most importantly clean. You can also remove the tray,and keep the baby buckled in while you tidy up. Fabulous	2
13	My child is scared of "big potties". When we are on the road or out shopping, this is the lifesaver for "I have to pee now daddy!". We love it.	2
18	It does the job, but in one travel, it had 2 holes probably from the way the airlines handle the things. But it does keep the car seat safe and clean. The quality is pretty good.	2
38	The chicco car seats are great - easy to use, high safety ratings, and nice looking. My only complaint about this car seat is that my son sweats like crazy in it. We live at 7,000ft so not in a warm climate by any means - houses where we live don't even have AC. I could not imagine how much he'd sweat in a warm or humid climate. Even after short rides in a well ventilated cool car his head totally soaks the head rest and the back of his shirt is totally soaked through. Going to look at other options for our next baby as our son loves his car seat and going for rides until he is soaking in sweat.	2
85	It doesn't really keep the car seat cool, but it does keep it cooler than the rest of the car, which is noticeable when you are in very hot temperatures. We traveled through areas with 3 digit temperatures (Texas, New Mexico, Nevada, Southern California, etc). The most important part is that the metal parts of the buckles don't get hot enough to burn the baby, and this is what it did. For the price, great product.	2
96	You can't put a price on your child's safety, but $60 plus for the car seat base it a little ridiculous.	2
124	This works great to entertain my 3 month old who gets fussy if the car seat isn't moving! It helps to keep him happy while I'm trying to pack up the car and get him situated. It's great for those down times when the car isn't moving yet.The only thing I do wish it had was an option to have it stay on for a few minutes. He's too little to hit the button himself to play the noises and lights so I have to hit the button and I can't safely do that from the front seat while we are driving!	2
148	We got this seat in Pink Mist at Target. It's awesome. The handle and overall shape is great, very easy to carry and move around. The seat is much lighter than many of the others we looked at but still sturdy. The seat is not bulky at all and leaves enough room for our older 2 to be able to buckle their seat belts in the backseat! The seat comes with an insert over the back to pad around babies head as well as a guard over the feet. Both of these are removable as baby grows. With our other kids we had to go out and get special inserts to go around the baby's head to keep them snug in their seats. No need here! This seat is designed for the safety of newborns. But again, you can remove the extra pieces for more space later when baby has more head control. The latches are a little pesky - you have to line up the two sides together before latching them into the center piece. But after a few tries you get the hang of it. It's very easy to adjust the straps with the slack and a release button located at the front of the seat. Love the base. Seat snaps in and out very easily and it's easy to belt into the car.Overall we're happy with the safety ratings, the design, especially the weight and ease of use, and we would recommend this seat!	2
154	I have been using this stroller for about a year for walks around the neighborhood, trips to the zoo, and parks. It is great on paved surfaces and packed sand/dirt park trails. My kid seems pretty happy in it.Pros:light (14lbs)compact (fits easily into my compact car trunk)roomy basket (my giant diaper bag fits in there)peekaboo window in canopyeasy to recline when kid is sleepingcomfort padding on shoulder strapsCons:the double rear wheels are close-set so I step on them sometimesdifficult to close upno cup holder (for the pilot!)	2
181	First, we love this stroller... Second, we love this travel system... Third, I figured out how to make the travel system even better for the early months when the baby isn't big enough to use the actual stroller alone and when mom is still recovering from child birth and every extra pound makes a difference when lifting.Here's what I did, I took the seat completely off the stroller and used the frame as a snap and go for the carseat. The seat is connected with velcro and a few snaps. The hardest part was taking the quick release handle off because it uses a keyring type of connection, but with a little work it comes off just fine. The entire process of taking the seat off took 10mins or less. Putting the seat back on took about the same time or just a little longer since I made sure I put it on correctly.This was awesome for many reasons:1. The carseat still snapped into the frame with no problems, because the clips are connected directly to the frame2. The stroller is lighter (at least a pound or two)! This made a huge difference for me being able to lift it in and out of the car3. The basket underneath is so much more useful. You can throw a huge bag in there because the seat is no longer in the way. We were also able to put folding chairs over the basket for a day in the park and the stroller held up great4. Takes up less space in the trunk because the middle of the folded stroller is now a space you can put other things (instead of putting things on top of the seat that was there)We have since put the seat back on the stroller because the baby is now able to use the stroller without the carseat, but consider this option for the early months. It saves you the money of buying a snap and go if you were considering that. Also, this way is much sturdier than a snap and go, because you still get all the great features of the B-Agile including its quick fold.Happy Strolling!!!	2
